To all whom it may concern:

Be it known that I, JOHN ATKINS, a subject of the Kingdom of GreatBritain, residing at 51 Snape Hill, Dronfield, Sheffield, in the countyof York, England, have invented certain new and useful Improvements inRolls for the Manufacture of Shovels, Spades, and Similar Articles, ofwhich the following is a specification.

This invention comprises improvements in the manufacture of shovels,spades and similar articles, and it has for its object to reduce thecost of manufacture without in any way detrimentally affecting thequality of the finished article.

The class of apparatus to which the present improvements relates is thatwherein the tang is introduced from the side at which the workman standsand is delivered toward him, such tang being operated upon by a rollhaving difierential diameters the larger of which rolls the tang and thesmaller constitutes a recess to accommodate the blade. This invention isdifferentiated therefrom inasmuch as in a single set of rolls mounted inone housing prints are combined with the differential roll in such amanner that the blank which enters the rolls finally leaves with theblade finished and the tang flattened.

According to this invention the blank is passed through the rolls todraw the blades and form the strengthened portion around the foot of thetang and in the same rolls the tang is rolled and flattened to asuitable condition for bending into the required configuration to formthe socket, the blade being unaffected during the rolling of the tang,thereby enabling a single heat to serve for carrying out such processesand obviating the necessity for reheating which has hitherto existed.The prints in the rolls for stiffening the blade are similar to thoseused heretofore but are all arranged on the one roll, so as to enabledifferent strengths and shapes of shovels to be operated upon whilereducing the number of rolls required to a minimum. 7 On the outerextremities of the roll spindles, spreaders of the known type aresecured for pressing out the tang to an increased width at its outer endso as to e11- able the socket when finished to eflieiently fit aroundthe taper handle of the shovel.

In order that this invention may be clearly understood and more easilycarried into blade around the root of the tang. Fig. 3 is a sectionalelevation on line Z Z of Fig. 1 showing the rolls during the operationof rolling the tang.

In an embodiment of this invention such as illustrated by the drawingsthe machine comprises two rolls A, B journaled in suitable housings Gwith spreaders D secured to the outer ends a b of the rolls A, B. Theprints or recesses c, f, y, it, j, 70, are pro vided to enable variousshapes and thicknesses of shovels to be dealt with for the purpose ofobtaining an increased thickness or rib around the root of the tang, thetang X itself lying in the upper elongated portion c ofthe print 6during such operation. In such process of rolling the blade the workmanstands at the front of the rolls, places the tang X and rib portion X ofthe blank in one of the prints 0, f, g, it, y, or is and allows theblank to pass through the rolls as shown by Fig. 2 to have the bladerolled and be discharged on the rear or reverse side of the machine.After the blade Y has been finished by the print the tang X is insertedand successively passed through the prints a a so as to partially drawit and prepare it for its final passage shown by Figs. 1 and 3, the rollA being of differential diameters a, a the latter of which forms anopening a wherein the blade Y may lie clear of the enlarged portion awhile such portion a. performs the operation of rolling the tang. Theshoulder a of the large diameter a is adapted to commence its contactwith the blank at the junction Z of the tang X and blade Y as shown byFig. 8. For shaping the tang the man goes to the rear of the rolls andplaces the tang in the space a in such a position that when the edge aof the roll A arrives at the center, the shoulder of the tang is grippedand goes in flush with such edge a and is carried through by theapproaching solid face a of the roll A in a direction toward the man,being held by him until released from the rolls. It will be readilyunderstood that several of the processes for rolling the tang may beeffected by the workman without releasing the blank by reason of thelatter approaching instead of receding from him, as is usually the case.The tang X which is then of a uniform width is gradually and laterallyspread by traversing the space d intermediate to the Spreaders D, untilthe width at its outer end is suflicient to form the enlarged portion ofthe taper socket, the subsequent operations of shaping s'uch socket andattaching the handle being effected in any convenient "manner.

Having now described my invention I declare that what I claim is z 1-. Apair of rolls for the manufacture of shovels, spades and similararticles, one of which has two portions of differential diam- "etersarranged in such relation that the larger of such portions is adapted toroll the tang of the shovel or other article, and the smaller or cutaway portion forms an opening wherein the blade thereof may lie clear ofthe rolls when rolling the tang, in combination with prints whereby theblank which enters the rolls finally leaves with the Q blade finishedand the tang flattened substantially as herein set forth.

2. A pair of rolls for the manufacture of shovels, spades and similararticles one of nation with prints whereby the blank which enters therolls finally leaves with the blade finished and the tang flattened, andspreader-s whereby the tang is gradually spread ready for beingformedinto the socket, substantially as herein set forth.

In witness whereof I have hereunto set my hand in the presence of twowitnesses. JOHN ATKINS.
